The method of making the hydraulic trailer axle have?

Traditional hydraulic trailer axle axle in the middle part of a trapezoidal structure, on both sides of the cylindrical structure, the axle with integral forging forming, complex manufacturing process, quality, and weight. Axle trapezoidal structure parts set with king pin holes, king pin hole with copper bushing, regular lubrication maintenance. Utility model content the utility model technical problems to be solved is to provide a guarantee the overall strength, reduce weight effectively applied to the hydraulic trailer axle. In order to solve the technical problems, the utility model including axle, king pin hole, copper bushing, wheel hub, described in the axle by forging long long axis of the solid and thick wall steel pipe by steel compound and into, described the king pin hole is set on the thick wall steel pipe. According to the above scheme, described in the axle box structure. According to the above scheme, described copper bushing bushing for polymer materials. The utility model beneficial effect has the following several aspects. 1. The light axle compound method to achieve the axle. 2. Polymer bushing has realized the self-lubricating, free maintenance.
